The Phase 1 clinical trial (CTR20240663) was a randomized, open-label, first-in-human study involving 92 participants, designed to assess the bioavailability, pharmacokinetics (PK), pharmacodynamics (PD), safety, and tolerability of GZR18 tablets in healthy adult participants. The study also evaluated the effect of meal timing on the drug's PK, PD, safety, and tolerability.
In this study, GZR18 tablets were safe and well-tolerated, with the most common adverse events being gastrointestinal reactions, consistent with the established safety profile of GLP-1 based therapies. PK data indicated favorable absorption, supporting a once-daily oral regimen. Both single and multiple doses showed a dose-response relationship in terms of PK and PD parameters. Participants treated with the target dose of 60 mg daily for two weeks exhibited an average weight reduction of 4.16% from baseline. Furthermore, a week after stopping treatment, subjects continued to lose weight 0.51%, reaching an average total reduction of 4.67% compared to baseline. At 21 days after discontinuation, neither the participants' body weight nor BMI had returned to baseline values.
About GZR18 Tablets
GZR18 tablet is an investigational, once-daily oral GLP-1 receptor agonist developed by Gan & Lee Pharmaceuticals. It utilizes a small molecule absorption enhancer, SNAC (N-[8-(2-hydroxybenzoyl)amino] caprylate), to facilitate drug absorption in the stomach by resisting pepsin degradation, thus prolonging the drug's half-life and enhancing its bioavailability. GZR18 tablets are currently in global Phase 1 clinical development.
